Given the difficult conditions of pumping out of the Hazel <br />A, and the steep, narrow haul road to the dump point, it is estimated that <br />no more than two cycles per hour can be completed, i.e., 10,000 gal. per <br />hour. <br />Thickener tank volume = 75,000 qal. (from COM, Inc. adequacy response, <br />dated 6/1/95). <br />Hazel A volume = 615' x 5' x 7' = 21,525 cu. ft. = 161,007 gal. (Letter <br />from Mark Steen dated 9/23/85 and located in File No. M-83-141). <br />Total volume of liquid and tailing to be pumped and transported is 236,000 <br />gallons. At 10, 000 gal. per hour, total pumping time is 23.6 hours. <br />Adding 6 hours for mobilization and demobilization of men and equipment <br />for a total of approximately 30 hours. <br />30 hours at $252 per hour: TOTAL JOB COST = 57560 (includes o&p) <br />+ 5 percent per Rule 4.2.1(5): 378 <br />GRAND TOTAL......$7938 <br />TOTAL ADDITIONAL BOND DUE IS $7938.00 <br />
